The Great Divorce

A short novel about a field trip to Heaven from Hell. The premise was interesting, that a busload of people in hell (described as a city where you can build houses with your mind but the houses have no roofs and you're always fighting with your neighbors and moving farther away from them) would take a trip to heaven - presumably with the ability to stay if they so choose - and the excuses they come up with to remain in hell instead (and alternatively, the reasons they feel they should be allowed to stay without understanding what staying really means). It's told from the perspective of a nameless Ghost who visits heaven and overhears many of the conversations of his fellow Ghosts, each of whom has a discussion with a teacher Spirit.

Also contained an interesting bit about earth, heaven, hell and purgatory, and how each of those can be perceived as being located in the place of official Heaven and Hell depending on your perspective.

Interesting to ruminate on. Not sure why I can't rate it higher. I've read other Lewis where I felt he was rather heavy-handed with the allegory (the latter books in the Space Trilogy come to mind), but this is not allegory. It was a good story, but I didn't love it.
